Below are a few additional tools to help you manage your workers' compensation claim:

Locate medical providers - Are you an employer or injured worker looking for doctors, hospitals or pharmacies? We can help you find local medical professionals.

First Fill program - The First Fill program allows one-time prescription processing before a workers' compensation claim is established, resulting in no out-of-pocket cost for the injured worker. Ask your claims representative for more details.
